In a previous page will be found an essay on the cultivation of the genus Correa, by Mr. B. Sanders, of Albany, to which we invite attention. The. London Florist figures, in its last number, the beautiful Correa cardinalis, lately exhibited by Messrs* Veitch & Son, at the Crystal Palace, as one of the most beautiful and interesting. In habit,. it resembles Correa ventricosa, but is far superior to that kind in odor and attractiveness, producing rich scarlet flowers an inch to an inch and a half in length, is an abundant bloomer, and of compact habit, and continues blooming longer than any other variety. Correaa are easily cultivated, and should be more generally known.

Another new plant must not be forgotten - -the Pleroma elegans. This is one of the most beautiful summer and autumn flowering plants in cultivation; there is a neatness in the glossy green foliage and compact habit of well managed plants of it, that is at all times pleasing. And if we add to this the large, round, dark purple flowers which are produced on every branch in great abundance, we shall find that we have few plants more attractive.

Genus Correa #1

It is worth inquiring, whether the great demand for cut flowers in winter, in this country, does not cause a too exclusive selection of plants for that end alone, thereby often losing the great beauty of others, because not so well adapted for that purpose. So long as cut flowers are in demand, the gardener, however fond he may be of plants themselves, must use means best calculated to obtain them 5 but there are few places so close run to supply the demand, that a few plants may not be cultivated to advantage, sacred from the murderous knife, and much to the general appearance of the house.

Plants grown wholly with this idea, should be of the most faultless growth and shape, and placed in the most conspicuous parts of the house as starers. Two or three distinct kinds of the charming New Holland genus Correa, are admirably adapted for this purpose, being in flower for the greater part of the time they will occupy the greenhouse, and at their greatest perfection in mid-winter. Under good management, they are exceedingly quick growing plants, especially a variety called Lindleyana, forming, in twelve months, respectable sized flowering plants, and, in two years, good-sized specimens. The quality of the flowers of this genus, under the hand of the florist, had greatly improved, and there are quite a large number of varieties in cultivation. Harnrii, though raised many years ago, is still a good one; this, and the one named above, and the old speoiota, is enough for small collections. It is quite common for nurserymen to work the good kinds on alba, but they seldom make fine plants, and often grow very slow- - a plant from a cutting, even if very small, growing more in one summer than a worked one will in several.

The flowers are. drooping, and require to be tolerably .close to the eye to be seen effectually; hence, a bush inclining to a pyramidal shape, is to be preferred. Small trees or standards would look well, but it will take, a good long time to get4 them any size on their own roots, as none of the showy kinds swell to any size in the stem.
